In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners investigate the properties of graphene and graphite.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
